CINDER-DEFLEGTGR.

Specification of Letters Patent.

Patented June 3.,

Application filed December 5, 1912. Serial No. 735,164.

To all whom 1'2- moy con/corn:

Be it known that 1', DAVID A. Sox, a cite zen of the United States,residing at Can rollton, in the county of Carroll and State of Georgia,have invented a new and use ful Cinder-Deflector, of which the following is a specification.

This invention relates to an attachment to be positioned upon the stilesof a car win dow, in order to prevent cinders from entering the saidwindow.

The object of this invention is to provide a device of simpleconstruction which will deflect the cinders and prevent them fromentering the car window and is further adapted to protect one of twowindows according to the direction in which the car upon which my deviceis installed, is travelmg. I

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention. In the drawings accompanying this specification and forming apart thereof, the preferable form of my invention has been illustrated,in which- Figure 1 isa view in elevation of a sec tion of a car with myimproved cinder deflector in position thereon. 2 is a view inperspective of my improved cinder detlector, and 3 is a verticalsectional view taken through the central portion of the above. Fig. 4 isa sectional view on the line A+A of Fig. 2.

Referring to the drawings in which similar reference numerals designatecorre sponding parts throughout the several views, 1 represents the sidewall of a pas scnger coach which is provided with a plurality of windows2 having the usual stiles or upright posts 8 therebetween. The l0ngitudinal sill is represented at 4 and has the usual outward anddownward inclination.

Mounted upon the stiles 3 is my improved deflector which is preferablymade from sheet metal, it being understood in this con nection that I donot wish to limit myself to the use of metal as it will be readilyapparent that other materials might be used in order to secure thedesired result. The cross sectional VlQW, illustrated in Fig. -t showsthe deflector to be substantially trianguiar in outline and composed ofthe wings or walls 5 and 6 meeting at a line or apex 11 to define anacute-angular edge. Formed integral with the side wings or walls are theoutlying extensions or securing flaps 7 and 8. These flaps are providedwith a suitable number of apertures 9 there in through which suitableretaining means such as screws or nails are passed to thereby securelyhold the deflector in position upon the stile.

The lower extremities of the side wings or walls 5 and 6 are obliquelyinclined as illustrated in Fig. and have extending therebetween atriangular reinforcing web 10. This formation allows the lower end ofthe deflector to fit snugly against the window sill The upper end of thedeiiector is formed by the extensions 12 and 13 of the side walls 5 and6 respectively, these extensions being arcuated or domed and meeting toform an acute angle on the quadrantal line 1% which is in continuationof the vertical acute-angular outer edge 11 and terminates at theuppermost apex 1h,the purpose of this rounded upper ribbed dome shapedend being more fully hereinafter set. forth.

With my inu roved duplex or double cinder deflector mounted in pos ionupon the stiles between the windows it will he apparent that a singledeflector will serve as a. shield for either of two windows according tothe direction of t are]. of the car. By the particular coniornution ofthe upper extreme end thereof. the cinders in falling downwardly willalso be deflected away from the car windows, which is very essential ina device of the class described. The triangular ihrnuition of the sidewalls will cause a draftor current of air to flow outward and away fromthe car window which current of air will carry therewith cinders anddust and to thereby prevent the same from enteringthe car; y

The efiiciencyot a device of this kind is directly proporticnat theadoption of a transverse or cross tional form, which is a mean betweenthe two extremes represented respectively by a flat plate or board ezctending directly outward from the wall of the car and an inclined orhorwontally' V- shaped structure, in which the faces are disposed atsuch an angle to each'other (as for example, a right angleor obtuseangle) as to permit cinders, smoke and dust to find their way around theouter edge, by reason of not being positively projected or deflectedoutwardly or from the car by impact against that face of the deflectorwhich is forward. board or plate, the suction produced in rear thereoiis suflicient to neutralize to some extent the deflecting effect of thedevice, by drawing a portion of the dust and smoke into the space inrear thereof, from which point it can gain access to the window, andwith relatively obtuse-angled deflector the surface against which thedust and cinders strike does not serve to project the materials outwardfrom the car wall with suflicient positiveness, and this fact applieswith equal force to the upper end of the deflector, which must be reliedupon to take care of those cinders which approach the deflector fromabove or in a downward and rearward direction, with reference to thedirection of movement of the car,

By providing a deflector with faces disposed in an outwardly convergentrelation with reference to the car wall, so that they meet to define anacute-angular vertical edge which merges at its upper end into aquadrantal curve which maintains the acuteangular transverse formationand extends inward to the side" of the car, or to what maybe termed thebase or securing plane of the deflector, the downwardly and rearwardlyapproaching cinders are effectively disposed of, and are deflected insuch a way as to prevent them from finding their Way over the deflectorto the zone in the rear thereof, and thus from gaining access to thewindow. At the same time, the downwardly and outwardly inclined loweredges In the case of a fiat deflector of the wings of the deflectorembodying my invention, in addition to conforming to the sill of thestandard car, serie to neutralize any tendency of dust to pass under thedeflector and thus enter the zone in rear of the same. The reinforcingweb, in addition to strengthening and stiffening the structure at itslower end, serves to exclude moisture from the space between the wingsor walls and prevents the formation of a suction at that point shouldthe deflector overhang the outer edge of the car window sill.

Having thus fully disclosed the construction and operation and pointedout the advantages of my improved cinderdeflector, what I claim to benew and original with me is A cinder-deflector for carwindows designedfor attachment to the exteriorsurface of a car wall between adjacentwindows and above thesill thereof, the same being horizontally V-shapedand comprising angularly disposed wings or walls connected at theirfront edges to define a vertical acute-angular outer edge and curvedtoward each other at their upper ends to form a dome, and meetingtodefine an acute angle on a quadrantal curve in continuation of saidvertical outer edge, the lower edges of the sides or wings beinginclined downwardly and outwardly to conform to, and

bear upon, the Window sill. and form cinderdeflecting elements proecting below the plane of the window opening, and a web or plateconnecting the wings or walls at their lower ends.

In testimony that I claim the foregoing as my owngl have hereto affixedmy signature in the presence of two witnesses.
